Upshift prompt for fuel-economy-optimised
driving
The consumption-oriente
d upshift indicator A in
the tachometer at the ri ght beside the digital
speed display helps you to develop a fuel-saving
driving style.
The upshift indicator lights up - prompting you to
shift up to the next-higher gear - depending on the
selected gear, engine speed and accelerator
pedal position.
The upshift indicator is only active when “Sport” or
“Sport Plus” mode is switched off.
f Change to the next-higher gear when the
upshift indicator lights up. Shifting down –
f
Pull the PDK selector lever or shift button on
the steering wheel back.
You can shift up or down by the corresponding
number of gears by quickly pressing or pulling the
shift buttons or selector lever several times in
succession.
The transmission can be shifted up or down by
several gears in succession by continuously
operating the selector lever or shift buttons.
You can shift up or down at any time depending
on driving speed and engine speed.
Gear changes that would exceed the upper or
lower engine-speed limit are not executed by the
control unit.
There is no automatic upshift at the upper engine-
speed limit in selector-lever position M. Upshift
suppression can be cancelled by kickdown
operation. If, for example, the engine-speed limit
is reached during overtaking and an automatic
upshift does not occur, the transmission shifts up
in this case as a result of kickdown operation.
f Select an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking. To shift up automatically
at the upper engine-
speed limit:
f Press the accelerator pedal beyond the full-
throttle point (kickdown).
Failure of the selector lever display on the
instrument panel
The warning “Gearbox emergency operation”
appears in red on the multi-function display.
Effect:
– No selector-lever position is displayed on the instrument panel.
Vehicle can be driven only until it comes to
astop.
Action required:
f It is not possible to continue driving. Stop the
vehicle immediately in a suitable place. Have
the vehicle towed to a qualified specialist
workshop.

Driving and Driving Safety
Porsche Traction Management
(PTM)Porsche Traction Management is an active all-
wheel control system designed to influence
longitudinal and lateral dynamics. It is closely
linked with the Porsche Stability Management
(PSM) system.
The permanently driven rear axle enhances the
vehicle’s sporty features. Drive power is
distributed fully variably to the front axle,
depending on the driving situation.
In conjunction with PSM, the PTM system ensures
perfect distribution of power among all four
wheels in every driving situation. This improves
traction and driving stabil ity and ensures the same
high level of agility and dynamic response.
Warning!
In spite of the advantages of PTM and four-wheel
drive, it is still the driver’s responsibility to adapt
his driving style and maneuvers in line with road
and weather conditions, as well as the traffic
situation.
The increased safety that is provided should not
induce you to take greate r risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with PTM or four-wheel drive.
Risk of accidents due to inappropriate speed
cannot be reduced by PTM or four-wheel drive. Advantages of PTM
– Clearly perceptible improvement in traction,
driving stability and steering ability of the
vehicle.
– Vehicle is more manageable when driven at its performance limits.
– Improved straight-ahead tracking and greater stability.
– More sporty vehicle setup while making full use of all the advantages of four-wheel drive.
– ASR and ABD further enhance traction for all wheels.
For information on ASR and ABD:
f Please see the chapter “PORSCHE STABILITY
MANAGEMENT (PSM)” on page 202.
Porsche Stability Management
(PSM)PSM is an active control system for stabilisation of
the vehicle during extreme driving maneuvers.
It operates together with the Porsche Traction
Management (PTM) system provided the vehicle is
fitted with the relevant equipment.
PSM makes use of both the ABD and ASR
systems, as well as the known functions of the
anti-lock brake system (ABS) and engine drag
torque control system (MSR).
Warning!
In spite of the advantages of PSM, it is still the
driver’s responsibility to adapt his driving style and
maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with PSM.
Risk of accidents due to inappropriate speed
cannot be reduced by PSM.

Driving and Driving Safety
HOLD function: Drive-Off Assistant and
standstill management The HOLD function assists the driver when
stopping and driving off on upward slopes.
The vehicle is automatically prevented from rolling
back away from the desired direction of travel.
When the HOLD function is active, the function
light on the instrument panel lights up.
When adaptive cruise control is operating
normally, the HOLD function holds the vehicle
following automatic braking until the vehicle is
actively held in a stationary position.
Notes on operation
The HOLD function is no t available if the PDK
selector lever is in position N.
If the PDK selector lever is moved while the
HOLD function is active, the HOLD function is
deactivated.
If the driver’s seat be lt is unbuckled and the
driver’s door is opened wh ile the HOLD function is
active, the electric park ing brake is activated
automatically.
For information on the electric parking brake:
f Please see the chapter “ELECTRIC PARKING
BRAKE” on page 171.
Warning!
In spite of the advantages of the HOLD function, it
is still the driver’s responsibility to adapt his
driving style and maneuvers in line with road and
weather conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greate r risks with your safety.
Caution!
If the vehicle comes to a stop on a steep
uphill gradient without operation of the
footbrake by the driver, this may result in a
certain roll-back before the vehicle is held by
the HOLD function. In this situation, the roll-
back can be reduced by operating the
footbrake.
f Assist holding of the vehi cle by increasing the
brake force with the footbrake.
Brake pedal feels different. When adaptive
cruise control is operating normally or when
the HOLD function is active, the brake pedal
may feel different and you may hear
hydraulic noises.
This behavior is no rmal for the system.
It is not a fault.
Danger!
Risk of accidents. The limits set by physics of
driving cannot be overcome, even with HOLD
function. The responsibi lity for stopping and
driving off on uphill gradients is still the
driver’s, despite the HOLD function.
Assistance by the HOLD function is not
always guaranteed when stopping and
driving off on a slippery surface (e.g. on icy
or loose surfaces). In this case, the vehicle
can slip.
f Always adjust your driving style to the driving
conditions and vehicle load. Use the footbrake
if necessary.
If the Drive-Off Assistant is not functioning,
the driver cannot be assisted when driving
off on hills.
f Hold the vehicle with the footbrake.

ABS Brake System
(Anti-Lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the
driver’s responsibility to adapt his driving style and
maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physic s of driving cannot be
overcome, even with ABS.
Risk of accidents due to inappropriate speed
cannot be reduced by ABS.
ABS ensures
– Full steering control
The vehicle remains steerable
– Good driving stability
No skidding due to locked wheels
– Optimum braking distance
Shorter stopping distance in most cases
– Prevention of wheel locking
No flat spots on the tires Function
The decisive advantage of ABS lies in the driving
stability and maneuverability of the vehicle in
hazardous situations.
ABS prevents locking of
the wheels during full
braking, on almost all road surfaces, until just
before the vehicle stops.
ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable
with extremely rapid cadence braking.
The pulsating brake pedal and a “juddering noise”
warn the driver to adapt his driving speed to the
road conditions.
f If full braking is necessary, press the brake
pedal fully during the whole braking operation,
even though the pedal is pulsating. Do not
reduce brake pressure. If the ABS warning light lig
hts up on the instrument
panel while the engine is running, the ABS has
switched off because of a fault.
The warning message “ABS failure” appears on
the multi-function display in the instrument panel.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
In this case, the brake system will operate without
lock prevention, as on vehicles without ABS.
f Adapt your driving style to the changed
braking behavior.
The ABS must be checked by your authorized
Porsche dealer in order to prevent the
occurrence of further faults with unpredictable
consequences.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with no n-approved dimensions can
lead to different wheel speeds, causing ABS to
switch off. Warning light USA

Porsche Dynamic Chassis Control
(PDCC) FunctionThe Porsche Dynamic Chassis Control (PDCC)
system used on vehicles with air suspension is
a system for roll stabilisation of the vehicle body
when driving.
Driving comfort and driving safety are improved
by active intervention of the anti-roll bars on the
front and rear axles. Ve hicle balance and agility
are optimised.
No separate controls are available for the PDCC
system.
When you select a chassis setup in Porsche Active
Suspension Management (PASM) with air
suspension and level control, the PDCC system
automatically activates the corresponding on-road
driving program.
For information on selecting a chassis setup:
f Please see the chapter “PORSCHE ACTIVE
SUSPENSION MANAGEMENT (PASM) WITH AIR
SUSPENSION AND LEVEL CONTROL” on
page 209.
Warning messageThe warning message “Fault PDCC” or “PDCC
failure” appears on the mult i-function display in the
instrument panel if there is a system fault.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
f Adapt your driving style according to the
changed conditions.
f Contact a qualified specialist workshop in
order to correct the fa ult. We recommend that
you have an authorized Porsche dealer to do
this work, as they have the trained workshop
personnel and the necessary parts and tools
for this type of work.
Checking hydraulic fluidThe hydraulic fluid is checked and changed
regularly as part of servicing.
For information on maintenance:
f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on page 252.

Driving and Driving Safety
“Sport” and “Sport Plus” Mode FunctionThe selectable chassis settings mean that the
vehicle can offer various modes for a sportier
overall setup.
When “Sport” or “Sport Plus” mode is selected, all
the vehicle’s control systems are intentionally
shifted towards greater agility and driving
performance:
– PASM (Porsche Active Suspension Management) is automa tically changed to
“PASM Sport” or “PASM Sport Plus” mode,
resulting in a stiffer suspension setup.
The vehicle switches to Low Level in “PASM
Sport Plus” mode.
f Please see the chapter “PORSCHE ACTIVE
SUSPENSION MANAGEMENT (PASM)” on
page 208.
– Just like PASM, PDCC is switched to the corresponding “Sport” or “Sport Plus” mode,
whereby the rolling movements of the vehicle
are reduced further, depending on the
selected mode.
f Please see the chapter “PORSCHE DYNAMIC
CHASSIS CONTROL (PDCC)” on page 211.
– The PDK transmission switches to a sporty gear-changing map and shortens the gear
shifting times when Sport mode is activated.
Gear changes take place faster. f
Please see the chapter ““SPORT” AND “SPORT
PLUS” MODE” on page 195.
– The electronic accelerator pedal reacts sooner, and the engine is more responsive to
throttle inputs. When Sport mode is switched
on and the vehicle is travelling at a speed of
less than 25 mph (40 km/h), this function is
activated only after the driver has floored the
accelerator pedal or released it briefly.
– The rpm limiter characteristic is “harder”. In other words: the engine is immediately
throttled when the performance limits are
reached (only in manual selection mode on
vehicles with PDK).
– The turbo overboost briefly increases the engine boost pressure in the engine speed
range from 2,500 rpm to approx. 4,000 rpm.
As a result, torque in this speed range is
increased by 70 Nm (52 ftlb.). This
considerably improves acceleration and
flexibility, particularly in the medium engine
speed range. This does not affect the
maximum power. Quickly flooring the
accelerator pedal acti vates turbo overboost
in the engine control system. Overboost has
an effective operating time of approx.
10 seconds. After this time, it can be re-
activated by quickly flooring the accelerator
pedal again. – PSM (Porsche Stability Management) control is
more sporty in “Sport Plus” mode. PSM
interventions are later than in Normal mode.
The driver can maneuver the vehicle with
greater agility at it s performance limits,
without having to dispense with the assistance
of PSM in emergency situations. This helps to
achieve optimal lap times, particularly on race
circuits with a dry road surface.
f Please see the chapter “PORSCHE STABILITY
MANAGEMENT (PSM)” on page 202.
– Adaptive cruise control regulates speed and distance more dynamically.
– The Auto Start Stop function is deactivated.
f Please see the chapter “AUTO START STOP
FUNCTION” on page 169.
– The rear spoiler extends earlier and retracts later (“Sport Plus” mode only).
f Please see the chapter “RETRACTABLE REAR
SPOILER” on page 214.
– The system switches from High Level.
f Please see the chapter “HIGH LEVEL” on
page 209.
